How we build a shower that lasts
We build showers as a continuous waterproof assembly, not a stack of hopeful layers. That means a pre-sloped pan or sloped mortar bed at the correct quarter-inch-per-foot fall, a bonded waterproof membrane over the substrate, and corners, curbs, and penetrations detailed with the manufacturer's own components rather than whatever caulk is on the truck.
Niches and benches are where most failures start, because they create horizontal surfaces and inside corners in the wettest part of the room. We slope every niche sill, waterproof it as a unit, and place the seams away from the water path. It takes an extra half day and it is the difference between a twenty-year shower and a five-year one.
- Bonded sheet or liquid membrane systems over a pre-sloped base
- Correctly detailed corners, curbs, benches, and sloped niche sills
- Linear and center drains set to the slope, flood-tested before tile
- Frameless glass, tiled ceilings for steam, and full-height surrounds
